This is my first bit of confusion - after I've cast off the first 2 on the next 12 rows (which would be 32 - 24 = 8), what does the next line mean by "12 sts"?

NEXT PROBLEM:
Within the pattern for the front it asks me to 'wrap' (which I get) then 'turn'. Do I literally just turn the knitting over and then carry on?

NEXT PROBLEM:
Left front:
Cast on 18
3 rows follow, then
"Knit to last 4 sts., pick up loop between last and next st and knit into the back of this loop. K1, p1, k1, p1. 19 sts."
Repeat last 2 rows 27 times. 46 sts"

I think I follow this up to "19 sts" but again I'm
not sure what the "19 sts" and "46 sts" means.
